Concrete slab for Heating pump...help!

I am buying a house in a couple weeks. The 2.5 ton gas/air unit is going to be replaced. The concrete slab needs to be raised 1.5" on the front end as it has tipped. I am being told insead of lifting the 4x4' 6" thick slab, just re-frame it and add new concrete to level it out is as the dirt is settled. 1st off it is 37-45 degrees now and pouring new concreat on the old may not stick together. Should I drill holes in the old concrete slab so the new concrete goes in there or should I used some type of reinforcment? Again, it only has to be raised 1.5". Thanks for any help!

Might check at a supply house like Johnstone supply. We now use a ultralite condensing pad. You can just put this on top of what you have and shim it level.

I've also seen them "not sure if it's the same brand" but they have adjustable legs.

Use a wrecking bar and raise it up and fill underneath it, a 4 x 4 slab is not that heavy.
